Question

Carlos used the drawing below to help explain how he found the area of the right triangle. Which expression shows the correct process to find the area of the right triangle?

Answer 1

The area of a right-angle triangle is; Area = a x b / 2

Explanation:

A right-angle triangle just like conventional triangle, has three sides.

The sides are labelled a, b and c. With a as the height of the triangle and b as the base and c as the slope or the hypotenuse.

The area of a triangle is: (base/2) x height

This is similar to the area of the right-angle triangle which is also half of the base multiplied by the height of the triangle, that is,

Area = ab / 2
